As your specialist practice for modern orthodontics in Cologne-Rodenkirchen, we at JUST KFOMany tooth and jaw misalignments are not caused by genetic factors alone. The way we breathe - especially mouth breathing - plays a decisive role in the development of teeth, jaws and the facial skull. In this article, we show you why early detection is so important, what consequences chronic mouth breathing can have and how orthodontics can provide targeted support.

Why do we breathe through our mouths?
Mouth breathing can occur temporarily with colds or allergies - this is completely normal. It becomes problematic when mouth breathing becomes a habit. This can be caused by
Enlarged pharyngeal or palatine tonsils
Chronically blocked nose (e.g. due to allergies or polyps)
Narrow nasal passage or malposition of the nasal septum
Habits in childhood (e.g. thumb sucking)
What effects does mouth breathing have on tooth and jaw development?
With regular mouth breathing, the natural pressure of the tongue on the palate, which is crucial for the correct growth of the upper jaw, is missing. The result: the palate remains narrow, the jaw does not develop symmetrically - and malocclusions such as:
Crossbite
Narrowness
Open bite
Protruding front teeth
Retraction of the lower jaw
In addition, chronic mouth breathing can also affect posture, lip function and speech. The development of the jaw and teeth is negatively affected by this habit.
Early detection is crucial
The earlier mouth breathing is recognized and orthodontically treated, the better subsequent damage can be avoided. The jaw is still malleable , especially in children. In our practice, we focus on holistic early treatment concepts - individually tailored to the needs of your child.
Orthodontics as part of an interdisciplinary treatment approach
In many cases, successful treatment is only possible in collaboration with other specialties. As mouth breathing can lead to health problems such as tooth decay and misaligned jaws, we at JUST KFO work closely together:
ENT doctors
Speech therapists
Pediatricians
Myofunctional therapists
to identify the causes of mouth breathing and treat them holistically.
